Vegetable Revival
Source Institutions
In this activity, learners use food scraps from the kitchen to grow new vegetables.

Modeling the Seasons
Source Institutions
This activity provides instructions for learners to create models of the Earth and then to model a "day" on Earth as well as modeling the seasons.

Pinhole Magnifier
Source Institutions
In this activity related to light and perception, learners use a pinhole in an index card as a magnifying glass to help their eye focus on a nearby object.

Tiny Pants Photo Challenge
Source Institutions
In this activity, learners use a simple trick of perspective to dress friends in tiny cutout clothing. Learners make tiny pants out of card stock and tape them to the end of a stick.

Circles of Magnetism I
Source Institutions
In this activity related to magnetism and electricity, learners create a magnetic field that's stronger than the Earth's magnetic field.

Greeting Card Boxes
Source Institutions
In this activity, learners make cool boxes out of old (or new) greeting cards or postcards.

Tape Electroscope
Source Institutions
In this simple activity, learners create an electroscope by sticking two short pieces of magic tape together and then pulling them apart to find the sign of the charge on an unknown charged object.

Dye Like A Natural
Source Institutions
In this activity, learners stain fabrics--on purpose!

Give and Take
Source Institutions
In this activity, learners explore liquid crystals, light and temperature. Using a postcard made of temperature-sensitive liquid crystal material, learners monitor temperature changes.

Finding the Sweet Spot
Source Institutions
In this activity, learners will discover how to find the "sweet spots" on a baseball bat. Whenever an object is struck, it vibrates in response.
Floating Paperclip and Other Surface Tension Experiments
Source Institutions
In this activity, learners experiment with surface tension using everyday household items such as strawberry baskets, paperclips, liquid dish soap, and pepper.

Fog Chamber
Source Institutions
In this weather-related activity, learners make a portable cloud in a bottle.

Indicating Electrolysis
Source Institutions
In this activity, learners build a simple electrolysis device. Then learners use an indicating solution to visualize hydrogen and oxygen molecules in water.

Soda Can Mirrors
Source Institutions
In this activity, learners explore how pictures change in curved mirrors. Learners make cylindrical mirrors by wrapping Mylar around soda cans.

Experimenting with Naked Eggs
Source Institutions
In this activity about osmosis, learners use a naked egg (one with a dissolved eggshell) to learn about selectively permeable membranes.

Evolution in Plane Sight
Source Institutions
In this activity, learners model directed evolution by making paper fly. Learners construct and fly paper airplanes.

Fading Dot
Source Institutions
In this activity, learners play with a fuzzy-colored dot that has no distinct edges seems to disappear. As learners stare at the dot, its color appears to blend with the colors surrounding it.

Mid-Air Maneuver: Skateboard Science
Source Institutions
To understand how skaters turn in midair, try this little experiment! Individuals can do this activity alone, but it works better with a partner.

Coupled Resonant Pendulums
Source Institutions
In this activity, learners discover that two pendulums suspended from a common support will swing back and forth in intriguing patterns, if the support allows the motion of one pendulum to influence t

A Simple Escapement Mechanism
Source Institutions
In this activity, learners build a simple mechanism that regulates the "escape" of energy released by a falling weight by portioning it into discrete amounts.
